Male Gecko Licking His Vent

LOG IN TO CLOSE THIS AD

Hey guys! so i posted a thread about my male geckos tail being skinny, and i felt like this needed its new thread because its a different situation.. but im sorry if im wrong and just spamming the forum!

ANYWAYS, so my gecko's Gnar's tail was skinner and i noticed today he was licking his vent. i think i saw just a little sliver of bright pink, so im assuming this is the start of inflamation and another partial rectal prolapse like he had last time. im planning on taking him to a vet on Monday, but i just wanted to know if this was anything serious or not. this may be the second time he has had inflammation, and im wondering if its because i have 3 dogs and 2 chinchillas as well as my two geckos, or if i just need to clean his tank better. or could it possibly be the source im getting my mealworms from or how i take care of my mealworms?? i get them from petco and just leave them right next to the tank and dust them. i just really need your thoughts!!

From your previous post, his tail didn't seem too thin and though the lighting for the photos are dark, he seemed to have decent weight. Sometimes my male leos will lick themselves after shedding, something just for no apparent reason. I chalk the last one up to how dogs or cats will lick themselves, akin to cleaning that area. That little sliver of pink you saw could very easily just been his hemipene and they will usually lick it after breeding.

Do you gutload the mealies at all? They (mealworms) aren't that nutritious of a feeder insect, for that matter most commercially available feeders aren't either, unless gutloaded up to 24 hrs prior to being fed off. The other problem with leaving them out is that will trigger metamorphosis, but keeping mealworms refrigerated denies them the ability to be properly gutloaded as the cold temps place them into a state of torpor.

He always has water in his bowl and each feeding I wet a paper towel for him... I dont gutload the mealies but his tail is skinnier from what it was before. When it's curved it looks fine but straight you can see it is smaller. Today I picked him up and saw that there was an opening near his vent, and I soaked him in sugar water and it closed. Tuesday or Wednesday I hope to have his poop tested just to make sure, because he has had inflamation before. Here are some more pics:

quick update! i dont know if he was doing it before but i left for a week long vaca and had my dad take care of him. he isnt eating unless i put the worms infront of him and even then he is picky. a few days ago i saw him standing in his corner where he usually pooped and he squeaked and looked like he was going to throw something up, but he didnt. today he did the same thing, and im very worried. he is an adult male gecko and he is staying in that corner a lot. (that corner is right where the undertank heating pad is.) im very worried could this be parisites or impaction?? i have a female and she seems pretty normal, fat tail, eating, except her poo is a bit runny.

I have tagged a user who has some very useful links that may be helpful to you and your Leo. Hopefully she will see your latest update. The only advice I can give is to bring him to your Vet as soon as possible. The dry heaving is definitely NOT a normal thing. Sorry I can't be more helpful, I am fairly new to this all myself. I wish the best for the both of you though!!

OKAY! so i took him to the vet and he was handling my gecko and rubbing his stomach i guess to check for impaction, but my gecko pooped a giant poop right on to his papers xD so i asked about a fecal exam and they did one and he is parasite free. he said some geckos stop eating for many reasons, and he said that mealworms tend to bind in the geckos stomach. anyways! although he still isnt eating, the vet told me to force feed him with critical care and im doing that, hopefully to trigger his appetite. he turns away from mealworms, so i may try crickets (although last time he seemed uninterested in crickets)

Interesting statement from your Vet Re: mealworms. I've seen similar in other desert species (collared lizards, various spiny lizards, whiptails, etc.), up to the point of these species regurgitating the mealworm meal. Myself and a more educated best friend of mine have chalked this up due to too many mealies combined with too low of temps for maintaining digestion. I've seen it happen with other insects too, but not nearly as frequently as with mealies and superworms. My best friend's assumption is outside of too much food and/or too low of temps, said binding or regurgitation is also linked to the more dense exoskeleton which sits "heavy" in the stomach.

Good thing on the parasites. What fecal exam was performed, float, smear, both? Going off the advise from a zoo keeper friend, I'd potentially suggest a 2nd and 3rd fecal exam. I did similar when I was the Museum Naturalist for the Las Cruces Museum of Natural History, having tested 4 of our snakes after a Work-Study cross contaminated water bowls. 1 snake with coccidia, pinworms, and tapeworm translated to other 3 getting coccidia and 2 popping positive for pinworms. The original snake with tapeworm went through 1 round of treatment of Droncit (praziquantel). At end of that treatment we fecal tested once, and at the recommendation of a zoo friend I had a 2nd and 3rd post-treatment fecal done. 3rd fecal popped positive for 1 tapeworm segment, which resulted in round 2 of treatment.

Still rambling...I do have some male leos that will go sporadic on eating when they are in breeding mode. If he got a whiff of a girl, or even a brief interaction (not necessarily breeding), I'm wondering if that triggered something innate?

im thinking of switching to another feeder worm, as he also doesnt like crickets. i will try raising the temp first though. i do have a female, except she is across the room from him. As for the fecal exam, they didnt really say which one they did. i heard of silkworms and phoenix (i think) worms, but i dont know which one is cheeper or which one provides better nutrition.

Very good to hear he is Parasite free! Hopefully the lack of appetite is an easy fix.
I just ordered Phoenix Worms for mine as he isn't a big fan of crickets either, nor am I due to the smell, a cup of 100 medium sized Phoenix Worms cost me $7.95 + shipping. I am heading out after work to get other food for him until they arrive. Thinking about Dubia roaches, not sure if the chitinous exoskeleton is as bad on them though.
